[0045] 参见图1和图1A，这儿称"参考位置"，它位于球棒头100上，杆颈中线102 (图1A)在虚拟垂直杆颈接口平面104 (图1)上，杆颈中线102与地平线108的着地角a约为60度。 [0045] Referring to FIGS. 1 and 1A, a here called "reference position", located on the club head 100, a hosel center line 102 (FIG. 1A) in the hosel imaginary vertical plane 104 (FIG. 1), the hosel center line 102 and 108 of the ground horizon angle a is about 60 degrees.平面104与杆头前缘111大体平行。 Plane 104 in the head 111 substantially parallel to the leading edge.除非另有说明，以下所有球棒头参数都指在参考位置。 Unless otherwise noted, all of the following parameters refer to the clubhead at the reference position.

[0046] 参见图1A和1B，如"球面中心"，面中心115位于模板114，跟-尖轴116a与下端-冠部轴116b构成垂直相交的坐标系。 [0046] Referring to FIGS. 1A and 1B, such as a "spherical surface center," the center plane 115 is located in the template 114, with - the lower end of the tip and shaft 116a - 116b constituting the crown axis perpendicular to the coordinate system.孔118在坐标系的起始处，轴按均匀分布的增量分级。 Hole 118 at the beginning of the coordinate system, the axis of graded increments evenly distributed.模板114可由弹性材料制成，如：透明聚合物。 Template 114 may be made of an elastic material, such as: a transparent polymer.

[0047] 球面中心115的位置按以下方法确定。 [0047] The position of the spherical center 115 is determined by the following method.首先将模板114贴在击球面106上，那么孔118大体位于击球面中间，跟部-尖部轴116a与杆头前缘111基本平行。 First, the template 114 on the ball striking surface 106, the aperture 118 is substantially in the middle of the ball striking face, a heel --111 substantially parallel to the axis of the tip portion 116a and the leading edge of the club head.然后沿着击球面106跟-尖方向来回移动模板，直到跟部与尖部到击球面对沿的测量绝对值相同为止。 Then along with the ball striking face 106 - movable platen back and forth direction of the tip until the tip of the heel to the ball striking face portion measured along the same absolute value is reached.一旦确定模板114在击球面106跟-尖方向的中心位置，模板要沿下端-冠部方向来回移动，直到下端和冠部到击球面对沿的测量绝对值相同为止。 Once the template 114 with the ball striking face 106 is determined - the position of the center of the tip direction, along the lower end of the template to - moving back and forth direction of the crown portion, until the lower end portion of the ball striking face and a crown measured in the same absolute value so far.重复以上步骤直到跟部和尖部，下端与冠部测量值相同，并与相应轴方向相反。 Repeat the above steps until the heel portion and a tip portion, a lower end portion of the measured values ​​with the same crown, and contrary to the direction of the corresponding axis.然后经过孔118在击球表面记录一点，这样球面中心115就确定了。 Then through the hole 118 in the record that the ball striking surface such that the spherical center 115 is determined.

[0048] 定位样板如模板114在《美国高尔夫协会高尔夫球棒头弹性测量程序》(2. 0版本，2005年3月25日修订）中有涉及，在美国高尔夫协会中也可见到。 [0048] positioning the model as a template in the 114 has "the United States Golf Association, golf club heads elasticity measurement procedure" (2.0 version, March 25, 2005 Revision) involved, the United States Golf Association can also be seen.

[0049] 参见图1C "甜点"，这儿指击球面106与虚拟线121的交点，虚拟线与击球面基本垂直，并穿过球棒头100重心。 [0049] Referring to FIG. 1C, "sweets", here refers to the intersection of the ball striking face 106 of the virtual line 121, a virtual line substantially perpendicular to the ball striking face, the club head 100 and through the center of gravity.

[0050] 这儿"自由质量"是指球棒头目标质量与球棒头最小要求结构质量之间的差。 [0050] Here "free mass" means the difference between the mass of the club head and a target minimum required structure quality of the clubhead.[0051] 参见图1D，根据本发明的一个或多个方面，球棒头100还可能包括下过渡区138，它在击球面106与下端部110之间。 [0051] Referring to 1D, the present invention according to one or more aspects of the club head 100 may further include a lower transition region 138, between which the ball striking face 106 and the lower portion 110.下过渡区的存在增加了击球面击球过程中的平均顺应性。 The presence of the transition zone increases the average compliance ball striking face in the process.平均顺应性的增加提高了从棒球头100到高尔夫球的能量传输，因此首球的球速与球穿行距离也提高了。 The average compliance increase to improve the energy transfer from golf to baseball head 100, so that the ball crossed the ball from the first ball is also improved.

[0052] 再参见图1D，下过渡区138还可能包括中心前天底126a，以棒头杆头前缘与虚拟垂直线128相交为特征，虚拟垂直线128位于虚拟垂直中心面128上，虚拟垂直中心面128与杆颈接口平面104(图1)基本垂直，并穿过球面中心115.如图1E所示，球棒头还包括中心后天底130a，它是球棒头下端部位110与虚拟线132的切点，虚拟线132位于中心平面124上，并与平面134垂直，与击球面106相正切于球面中心115。 [0052] Referring again to 1D, the lower transition region 138 may further include a central bottom yesterday 126a, the leading edge of the club head to club head 128 and intersects an imaginary vertical line is characterized by an imaginary vertical line 128 positioned on the imaginary vertical central plane 128, an imaginary vertical central plane 128 (FIG. 1) substantially perpendicular to the plane 104 and the hosel, and the virtual line 110 passing through the lower portion of the spherical center of the club head 115. As shown in FIG. 1E, further comprising a bottom center of the clubhead acquired 130a, which is tangent point 132, the virtual line 132 is located on the central plane 124 and a plane 134 perpendicular to the tangent to the ball striking face 106 with the spherical center 115.

[0053] 参见图1E和1F，中心天底角|3 1由地平面108和虚拟中心天底线136a组成，虚拟中心天底线136a穿过中心前天底126a和中心后天底130a。 [0053] Referring to FIGS. 1E and 1F, the central nadir angle | 3 1 from the ground plane 108 and the virtual center composition day bottom 136a, 136a virtual central bottom line through the center of the bottom day before yesterday acquired center of the bottom 126a and 130a.通过增加或减小中心天底角13 l，击球面106的顺应性也会改变。 By increasing or decreasing the center nadir angle 13 l, compliant ball striking face 106 will change.如，中心天底角13 1增加，那么球面106的顺应性也会增加。 For example, the center nadir angle 131 is increased, the spherical surface 106 will increase compliance.

[0054] 参见图1G，偏距天底角，如偏距天底角13 2位于相应虚拟垂直偏距平面上，如偏距平面125，它平行于中心平面124并与球棒头100相交。 [0054] Referring to FIG. 1G, offset nadir angle, such as nadir angle offset 13 2 located in the respective imaginary vertical plane partial anomalies, such as offset plane 125 which is parallel to the center plane 124 and 100 intersect the clubhead.每个偏距天底角都由地平面108与一虚拟偏距天底线构成，如穿过偏距前天底的虚拟偏距天底线136b，如偏距前天底126b，和通过相应共面偏距后天底，如偏距后天底130b。 Each nadir angle offset by a virtual ground plane 108 days baseline offset configuration, such as through the bottom offset from the day before yesterday virtual partial bottom line 136b, the day before the end of such offset 126b, and a partial distance through respective coplanar the end of the day after tomorrow, such as acquired offset bottom 130b.可通过上面描述的定位中心前后天底的方法来确定偏距前天底与相应共面偏距后天底。 The method may be positioned through the center before and after the above described determined nadir offset coplanar with a respective end of the day before the end of the acquired offset.

[0055] 为使顺应性变化也称恢复系数最小化，跨过棒头球面，跟部-尖部方向，从击球面106到尖部103和/或跟部105，球棒头天底角数值逐渐增大。 [0055] In order to restore the compliance of the coefficient is also called minimized spherical across the head, heel - tip direction from the ball striking face portion 106 to the tip 103 and / or heel 105, toe corner previous day value gradually increases.例如：中心天底角13 l(图IF)至少比偏距天底角P2(图1G)小5° 。 For example: the center nadir angle 13 l (FIG. IF) offset nadir angle than at least P2 (FIG. 1G) smaller 5 °.偏距天底角P2位于虚拟垂直偏距平面125上，平面125与中心平面平行且水平相距20毫米。 Offset nadir angle P2 is located on the imaginary vertical offset plane 125, a plane parallel to the center plane 125 and the horizontal distance of 20 mm.另一个例子，中心天底角Pl至少比偏距天底角|3 2小8° ，或最好比偏距天底角P2小1(T 。以上描述的棒头构造有助于维持美国高尔夫协会（USGA)最大可允许恢复系数（COR)，局限于球面中心处，同时能提高向尖部和/或跟部的球面顺应性。 As another example, the center than at least the nadir angle Pl nadir angle offset |. 3 2 small 8 °, or preferably more than offset the small nadir angle P2 1 (T club head structure described above helps to maintain the United States Golf the largest Association (USGA) allowable coefficient of restitution (COR), limited to the center of the sphere, while improving compliance to the spherical tip and / or heel.

[0056] 参见图1H和ll，下过渡区138可能还有一实际中心天底距152a，它在中心平面124上。 [0056] Referring to FIGS. 1H and ll, the lower transition region 138 and possibly a virtual center nadir distance 152a, it is on the central plane 124.实际中心天底距152a是中心前天底126a和中心后天底130a间最短距离。 The actual center nadir distance 152a is the end of the day after the shortest distance between the center of the bottom 130a 126a and center the day before yesterday.可通过改变中心天底距152a来改变击球面106的顺应性。 Compliance may be changed from the ball striking face 106 of the center 152a by changing the nadir.增加中心天底距152a可增加顺应性，减小天底距也可降低顺应性。 152a increases from the center nadir increased compliance, reduced from nadir also be reduced compliance.中心天底距152a为8毫米时较好，10毫米更好，12毫米最好。 152a nadir center distance is preferably 8 mm, 10 mm more, preferably 12 mm.[0057] 参考图1J和1K，实际偏距天底距152b是偏距前天底126a和相应共面偏距后天底间最短距离。 [0057] Referring to FIG 1J and 1K, the actual offset nadir 152b is offset from the day before the end 126a and the corresponding offset coplanar with the shortest distance between the end of the day after tomorrow.最好是偏距天底距比中心天底距152a(图II)大，这有助于提高击球面106的顺应性。 Preferably offset from nadir nadir distance than the center 152a (FIG. II) large, which helps to improve the ball striking face 106 of the compliance.如：偏距天底距152b比中心天底距至少大2毫米。 Such as: 152b offset from the nadir nadir than the center distance is at least 2 mm.大8毫米时较好，10毫米更好，12毫米最好。 8 mm is preferably large, more 10 mm, preferably 12 mm.
